This report contains abundance and specific composition data of 49 phytoplankton samples from the Upper St. Lawrence Estuary (summer 1982). Smayda's (1978) method for estimating phytoplankton biomass was applied to these data. Although more time-consuming, the plasma volume method yields a better image of phytoplankton biomass than traditional methods. Phytoplankton abundance is highest at the station located in the Lower Estuary; however, it decreases to considerably lower values in the Upper Estuary. Phytoplankton abundance reaches again higher levels in fresh water. In the Upper Estuary, microflagellates dominate the phytoplankton community. Biomass follows a similar pattern : it is highest in the Lower Estuary, lowest in the Upper Estuary and intermediate in fresh water. Ciliated protozoans are observed at all stations. Our observations suggest that the study area is not favorable for the development of local phytoplankton communities.
